Hot Water Cylinder News

McDonald Engineers has secured the contract to supply its CUBEflow Rectangular Thermal Store as a direct replacement for existing Elson units for the refurbishment of a busy accommodation centre in the North of England.

The company was asked to supply a 100 litre thermal store unit with all the connections in the exact same place as the existing rectangular tanks to enable the installation process to be quick and efficient.

McDonald Engineers also proposed the incorporation of a fully pumped system which would increase the efficiency of the system.

McDonald Engineers has reinforced its position as one of the UK’s leading manufacturers of commercial hot water cylinders with the delivery of two 500 litre POWERflow unvented cylinders for HM Prison Durham.

The bespoke cylinder was designed to include a removable battery to enable any maintenance to be carried out quickly and efficiently.

McDonald Engineers has reinforced its position as one of the UK’s leading suppliers of rectangular hot water tanks by supplying an electric CUBEflow to replace an Elson Coral tank for a housing project in London.

McDonald Engineers’ range of rectangular tanks has received unanimous praise since its launch for the quality and durability of the system with excellent feedback on the ease of installation – especially when replacing Elson rectangular tanks.

McDonald Engineers responded to a distress call from a 52 metre luxury Yacht which discovered a leak in a water tank only a few days before it was set to sail from its port in Majorca with a VIP guest.

Working to an extremely tight schedule, McDonald Engineers manufactured and supplied two 325 litres cylinders which were designed to work like an electric thermal store as well as being able to work in parallel during periods of peak demand.

McDonald Engineers have once again been shown to be the number one choice to supply hot water cylinders to the hospitality industry by having their Maxistore 7 direct vented hot water cylinder to the self-catering villas on the 5 star Duchally Country Estate.

Each of the 55 self-catering villas at the resort in the Scottish countryside features electric heating systems and McDonald Engineers’ Maxistore 7 is specifically suited to capitalise on off peak tariffs.

The life-threatening effects of contaminated water are well documented, however many people remain unaware of the extraordinary bacteria killing powers of copper which are clearly shown in 2 very simple tests conducted by McDonald Engineers.

Stagnant water sitting in a cylinder can be a prime target for bacteria such as Legionella, MRSA and ecoli, especially when the water temperature is allowed to sit between 20-55°C for a period of time – such as holiday periods or shut-downs.

Copper is widely recognised for its bacteria killing properties but if you were ever considering just how effective copper is when it comes to killing bacteria, here is the information you have been looking for.
MRSA - Copper alloys kill more than 99.9% of MRSA within two hours - Stainless steel did not exhibit any antimicrobial efficacy.
Ecoli - Over 99.9% of E. coli microbes are killed after just 1–2 hours on copper. On stainless steel surfaces, the microbes can survive for weeks.

McDonald Engineers had manufactured a 2000 litre solar pre-heat cylinder for 1 World Solar, who are installing 540 Thermomax evacuated tubes at Musgrove Park Hospital, Taunton. The project incorporated the 2000 litre cylinder, a 40 litre solar discharge vessel and 300 litre expansion vessel all mounted on to a steel skid plate. The highly technical project was part of the development of the Jubilee Building at the hospital. This will replace a series of temporary buildings at the site, and will make use of renewable energy sources.

McDonald Engineers’ ECOflow heat pump cylinder is available as a Tank On Tank system to reduce the space required and improve the installation process.

The tank on tank system is ideally suited for heat pumps which require a hot water cylinder and a buffer vessel. Heat Pumps have experienced a steady growth in the UK, however the traditional approach is to have a hot water cylinder plus a separate buffer vessel.
